Mods to check compatibility:

• Wings, Horns, Hooves (functions by default as they derive from AbstractHorse)
• Astikoor (Horse Carts) Moved to its own issue (#17)
• Horsebones not actually a mod

• 'Mo Creatures

• Zawa: Issues would require iterating over EntityTameable and then consulting the data manager (potentially) to determine if there's a saddle on the entity.

public boolean isOwner(final EntityPlayer player) { return player.getUniqueID().equals(this.getOwnerId()); }

I believe the ownership code is the same.

All of these issues have been resolved by the new compatibility system. It is simply a matter of confirming that it functions properly.

- Mutated Mobs: The only eligible mod is the spider pig which you can ride by default. I'm loath to add Animania-esque compatibility for something that doesn't even have the potential to be tamed.

- Rideable John Cena: Despite the glorious name, this is an MCreator mod which I will not support.

All of these have been resolved. All others are being tracked on discord.
